Title: Manufacture of chlorine hydrate
IPC: H01M8/06
Filed: 1972-11-14
Abstract: 1410949 Chlorine hydrate OMF CALIFORNIA Inc 14 Nov 1972 [18 Nov 1971] 52621/72 Heading C1A Chlorine hydrate is prepared by vaporizing liquid water, mixing the vapour with gaseous chlorine and contacting the mixture with heat transfer means having a temperature of from -50 C. to + 9 C. Preferably the liquid water is obtained from an aqueous metal chloride solution, e.g. zinc chloride, the chlorine is obtained at least in part from the aqueous metal chloride solution and both the metal chloride solution and the chlorine are effluents from a high density energy battery. The process may be conducted continuously. As shown in Fig. 1, a gas-tight walled reaction zone 11 is provided with an inlet tube 19 for water or aqueous salt solution, e.g. zinc chloride, to form a pool 23, the depth of which is maintained by an outlet 25. Electrodes 27-29 dip into the pool and are connected to a source of electrical energy whereby the liquid is heated and vaporized. Other heating means such as electric resistance heaters, steam coils, hot air heating, high frequency, induction or infra-red radiation heating may also be employed. The water vapour may alternatively be generated outside the reaction vessel. Above the pool is a perforated pipe 31 through which chlorine is introduced. To ensure an even supply of chlorine throughout the chamber the perforations may increase in size towards the downstream end or they may be of uniform size but increase in number toward the downstream end. Above the perforated tube 31 a cooling means 35 is installed through which the refrigerant flows countercurrent to the flow of chlorine. Tube 35 may be provided with fins to improve its cooling efficiency. If desired, tube 31 may be dispensed with, the gas passing in and out of the chamber through entry and exit tubes. The tube 35 may be of titanium or other corrosion resistant material such as glass or tantalum, or it may be made of titanium coated copper. The chlorine hydrate forms on tube 35 from which it can be removed by brushing or vibrating means.

As shown, each knob has an associated shaft and that of 345 has a cam 352 which co-operates with a lever assembly comprising cam follower 354, lever 355, gears 360, 361 to rotate gear 366 and hence pointer 370 located on the periphery of dial 343. Shaft 372 also carries a gear 374 whereby the pointer may be moved, by 10 times the amount that the same adjustment on dial 345 would give. In operation, one density value is set on dial 343 between pointers 370 and 382, these being a slip clutch between the knob and the dial for this purpose, and two parts of one of the other values, i.e. tenths and hundreds are set opposite the pointers on the other two dials. These settings consequently move pointer 370 to sum the two values on dials 341, 342 by the mechanism described. Knob 347 and dial 343 are then moved to indicate the third value on dial 343 opposite pointer 370, the difference on the dial 343 between the two pointers 370 and 382 giving the calculated fourth value, which may be displayed on a fourth dial. The input shafts may operate switches 350, 377 and 380 forming part of the photographic apparatus of Specification 1,361,021. Dials 341 and 342 may be coaxial, one shaft being hollow.

Title: Improvements in or relating to a circuit arrangement for a time-delay relay
IPC: H03K17/288
Filed: 1969-10-29
Abstract: 1280853 Discharge tube relay-operating circuits SCHARPENACK & CO 29 Oct 1969 [14 June 1969] 52975/69 Heading H3P An operating circuit for a time-delay relay includes a discharge tube in series with the relay and in parallel with a timing capacitor. As shown in the Figure, the circuit comprises a relay 9 arranged to operate a changeover contact 15. In use, when a supply is connected to terminals 1, 2, the capacitor 5 charges through resistors 6, 7, and, after a time determined by the setting of the variable resistor 6, becomes sufficiently charged to fire the tube 3. The current through the tube is now sufficient to operate the relay 9 and to changeover contact 15 so that a holding current can flow through a resistor 14 in series with the relay. The capacitor 5 can also discharge through the resistor 14, and the tube 3 ceases operation. If the relay is de-energized, or if the tube 3 does not operate, the capacitor 5 can discharge through another resistor 13, and a further discharge path may also be provided by way of the resistor 14 and a terminal 16.
